Global prevalence of temporomandibular disorders: a systematic review and meta-analysis
Abstract
Background: Understanding the global prevalence and characteristics of a given health problem is essential for sizing its global and regional burden, estimating treatment needs, prioritizing healthcare services, and formulating targeted policies. This systematic review and meta-analysis aimed to estimate the global prevalence of temporomandibular disorders (TMDs) by gender, age, and continent, and the prevalence of specific categories such as myalgia, arthralgia, clicking/joint sounds, and limited mouth opening. Methods: A comprehensive search was conducted across three databases—PubMed, Scopus and Web of Science and supplemented by manual search up to June 2024. TMD diagnoses were based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) or Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Results: The database search yielded 15,628 records, from which 27 studies involving 20,971 subjects, including 6075 diagnosed with TMDs, were selected for final analysis. All meta-analyses utilized a random effects model. It is estimated that nearly a third of the global population (29.5%) suffers from TMDs. TMDs affected females at a significantly higher rate compared to males (36.7% versus 26.7%), representing a 1.75-fold greater likelihood among females. Prevalence among individuals under 18 years of age is 38.5%, compared to 34.1% in those 18 and older. TMDs are most prevalent in Europe (33.8%), followed by Asia (27.9%) and South America (27.3%);…
